What a wonderful report, and how I envy your lack of pain. My knees are pretty much perfect, but oh the muscle problems I am having. On my Doctor's advice, I started on Alendronic Acid a year ago, as a bone scan showed I had just tipped over the line into osteoporosis. I was very reluctant as the leaflet said it could affect muscles and ligaments, and boy it has. A year later I am still stiff and in pain from them. I have weekly chiropractic treatment and as many massages as I can fit in. The drug also made my epilepsy worse, and I have had to have my drugs changed 6 times and cannot now swim or ride my bike. I can still dance if my muscles will let me, otherwise walking is my only exercise and that can be painful. I vary now from day to, last Friday I was pain free, Saturday all my muscles hurt. Today not so bad again. I am doing lots of stretches and other exercises. Still I am very pleased for you, last year I was doing just as well.
